Redirect bind requests to another server

Hello,

we have a web application that autenticates via openldap. Now a second hospital should use this same application, but they have their own autentication server, active directory in this case.

In our network the users authenticate giving their username ( amoroder in my case ) and password. Is it possible to configure openldap to redirect the bind request to the remote server when the username contains an extension like jsmith@remote ? Does this work with AD as second/remote authentication server ?

Thank you very much Andreas
